Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594436, here are decompositions:

7 + 31594429 = 31594436
37 + 31594399 = 31594436
43 + 31594393 = 31594436
103 + 31594333 = 31594436
127 + 31594309 = 31594436
163 + 31594273 = 31594436
199 + 31594237 = 31594436
277 + 31594159 = 31594436

Showing the first eight; more decompositions exist.
